摘要
在变导热系数条件下,把分段迭代法应用于解决非稳态导热物理问题的集总参数法,为敞口容器恒温热源加热过程中容器内的平均温度变化提供了一个简便的计算方法.利用该方法只需三次分段迭代,即可使得理论计算与实验数据结果吻合.
The piecewise iteration algorithm is applied to lumped parameter method for solving the physical problem of unsteady heat conduction in different coefficient of thermal conductivity. This new method provides a simple calculation for the temperature response curve of the open container heated by constant heat reservoir. The theoretical calculation is consistent with experimental result only after three piecewise iterations.
